This invention as indicated relates to a furniture brace. More particularly it com prises anapparatus for engaging thel endv posts of a framed article of furniture and applying tension to'said posts so as to ref tain the members of said .framed structure` 1in rigid lrelation to each other.

:The apparatus is designed to be readilyA .1 applied toza chair or other'article of furni-V ture with a minimum of effort and at the and related ends,.saidinvention, then consists of the means hereinafter fully described and.

particularly pointed out in the claim.

The annexeddrawing and the following description set forth in detail certain mech. anism embodyingv the invention, such disclosed means constituting, however, but

. several of *vario-us mechanical forms Yinwhich the vprinciple of the invention may 'be` y Y p f v f are connected to the terminal members .of the used. p

In said annexed drawing:

Fig. 1 is a bottom perspective view a chair equipped with tensioning apparatus' embodying the principle of myinvention;

Fig. Q is a perspective view of one form of terminal member for the turnbuckle; Figs.AV

3 and.4 are views similar to Fig. V2showing modified forms 'of terminal members for turnbuckles; Fig. 5 isa top plan view of a corner post bolt with a simple form of ad- Ajustable terminall member; Fig. 6 is an en' larged detail view,.partlyin'section showing' the adjustable terminal member illustrated in Fig. 5: Fig. 7 is a ydetailview ofa split ring used with the device shownA in Figs.

top plan view, with a portion shown sec-it tion, .illustrating the manner in which-fa securing bolt is connected with the corner post of a framed structure; Fig. 14 is a front elevation of a securing plate for,k cooperat-` ingwith a notched bolt stem; Fig.`15 is a .sec" 1 tional view taken along the line 15s- 15 shown Y in Fig. 14, looking the direction of the arrows; and Fig. lis a view showing ja' modified form of bolt and terminal member. As is clearly shown in Fig.f1of the drawing, the apparatus comprises a plurality of angle-.headed bolts 1 adapted to beengaged diagonally through the `corner posts 2 off'a vframed structure 3 and lhaving means ad-fy jacent their opposite ends adapted to be engaged -by a cable fastening device.

,1n Fig. 1 the bolt Shanks 4 are notched and are adapted to be engaged by Ushaped plates 5, which are adapted to be engaged by cablesorieX'ible members 6. In the form shown, the cables or ilexible members areV chains of standard form. The inner ends ofthe chains central tensioning device orl turnbuckle 8. Y

Several diEerent constructions for connecting the cable with the shank'of the corner post boltare illustrated. Int-he form shown in Figs. 5 kand 6, the angle-headed bolt 1, has a stem or shank 4, which is provided withr ya .series of circumferential notches havinginclined faces V11 cut so as to form shoulders 12 adjacent one side. r n

The'cable attaching device used with this form of construction comprises a plate 5 having itsends turned vup to provide l'a U- shaped member, the ends being provid'edwith apertures to vengage over the stem. Y Adjacent Vone, of theapertures, a circular seat '13 is provided to receive a split ring 14.l The split'ring is formed yof wire andV is of' a' size to snugly fit about the notched portion,` of the' stem behind one of theshoulders. It is placed in position by'spreading thering to slide over the main body portion of the stemv and then Vmoving it over 'the stem until a notch at the desired point of attachment of the cable to the stem is reached. When so engaged behind oneV of' the shoulders, the

plate is moved toward the ring sothat its; 100

tained upon the flexible member.

*below lthe position of said notches. The cable 8, notches are formed at intervalsalongl either side of the stem 16 by subjecting the stem to heavy pressure. This-provides a series of narrowed sections along the stem with a slight displacement of metal above and securing device for a bolt of the type shown :i-nFigQ-S- is--preferably formed-from a Jplate 'in the manner illustrated in Figs. 10 andI 11.

` The plate 1,-2 as shown is formed with an ellip- Qelongatedislot 19' throughout the remainder of its 'body portion. The elongated slot ends tical opening 1 8 adjacent o ne end and an ina narrow 'slot extension 215 at the opposite end of the plate, and the ends 22, 23,015 the plate are turnedupwardly. The plate las will be readily understood, may then be engagedv over the stem of the securing bolt by sliding the .end of' the stem through the elliptical aperture with the terminal loop of the flexible member engaged over the plate, and then l through the enlarged portion of the slot.

I fupon the stem of the bolt, the narrowed slot Whenitis desired to lock the securingv plate extension is engaged over one of the narrowed portions of the stem'. In order to lock the narrowed slot extension in secure en-V gagement with the stem, it is only necessary to draw the loop oftheV flexible member,

shown in the drawing as a chain link, toward that end of the plate. This willfirmly hold said endof the plate from movement to releasing position so long as tension is main- Y The pins are mounted in (see 2) plates 32,0f channel like form, having pairs of parallel ears 33 at each end apertured to receive the plate; A

' Another-form ofthe terminal is illustrated in Fig. Swherein'the bolt 41 is centrally secured in ai body member 42, the ends 43 ofsaid body member being slotted and bent upon themselves2 to engage the'pivot pins'44 upon which theJ terminal links of the respective chains may be engaged.

In the form of construction shown in Fig. 4, the plate for securing the flexible members to the turnbuckle is disclosed as comprising a metal strap 51 folded upon itself at either end to formloops 52 `and provided with al central aperture -within which a bolt V53 ris secured. I-n-Fig; 12 there is illustrated a terminal plate 54 fora corner post bolt 55 which is formed by'bending the'end's 5`6in parallel relation and providing them with oblique slots 57 to form hooks. In the rearward face of said plate a keyhole slot 5.8.is provided, the enlarged portion of whichis adapted to be engaged over the sternV of saidgbolt and the narrow Aportion of-'whichf is adapted to' engagel one of the notched'sections 59 along saidshank. I When a wire 61 is to-bev a plied to the construction of the character il ustratedi 4in Fig. 712,the wire Ymay be engaged vbetween the shank of the bolt andja rearwardly tu-rnedlip/62 tormedon said terminal member. The wire may then be threaded Vbeneath the ,hooks-and extended to any point desired.` f f In the -form of construction illustrated in Figs; 14 and 15 asmall-plate 63is. provided which is slotted at diagonal corners to provide a lseries of resilient tongues 64;- 'Said plate provided with a4 central .aperture 65-`- of somewhat `less diameter than that ofthe shank of the corner post bolts. 66 thus, when the plate is engaged'overk theshank of' said bolts, the. tongue portions lthereof will snap downwardly into the circumferential notches/3100 67 on said shank and will. serveas anabutment for locking anycable engaging member such as I have illustrated` in- Figs. 1i, 5, 8, 10, 12 and 13,4the keyhole slot or split ringbeing" omitted in such instance and openingsbeing'oi formed with a screw threaded'shank 73which is adapted vto beI engaged bya 'tubular lmember l74 preferably formed of a plate of material rolled to cylindrical form and having one* end formed into a hook75.

Other' modes of applying the principle of any invention may be employed instead ofthe one explained', change being made as VregardsY the mechanism herein disclosed, provided the" means stated by' therv following clai-m'or` the equivalent of such stated means befemployed.

I particularly point out and distinctly claim as my invention :f Y

A securing deviceV for'furniture braces, 125

comprising a terminal member having a shank, a fastening member having a body portion and angularly disposed en'ds-` provided with apertures adapted` to engage over-'said shank in freely slidable relationv thereto,

means permitting ,transverse movement of one end portion, and shoulder portions on said shank and fastening member adapted to interlock at predetermined spaced points of l adjustment along said shank, and a flexible member having a loop adapted to be engaged between said fastening member and said shank and movable longitudinally With respect thereto to a position below the transversely movable portion of said fastening member to latch said fastening memberv in predetermined adjustment With said shank.
